validate method

@override Future<void> validate(EngineContext context, Map<String, String> rules, { bool bail = false, Map<String, String>? messages, })

Validates the query parameters against the provided rules.

This method uses a Validator to check the query parameters stored in the EngineContext's query cache. If there are any validation errors, a ValidationError is thrown.

• Parameters:
  • context: The EngineContext containing the query parameters to validate.
  • rules: A Map of validation rules to apply to the query parameters.

Implementation

@override
Future<void> validate(
  EngineContext context,
  Map<String, String> rules, {
  bool bail = false,
  Map<String, String>? messages,
}) async {
  final registry = requireValidationRegistry(context.container);
  final validator = Validator.make(
    rules,
    registry: registry,
    bail: bail,
    messages: messages,
  );

  // Validate the query parameters in the context's query cache.
  final errors = validator.validate(context.queryCache);

  // If there are any validation errors, throw a ValidationError.
  if (errors.isNotEmpty) {
    throw ValidationError(errors);
  }
}
